Application of support vector machine with firefly algorithm for investigation of the factors affecting the shear strength of angle shear connectors

Abstract:

The factors affecting the shear strength of the angle shear connectors in the steel-concrete composite beams can play an important role to estimate the efficacy of a composite beam. Therefore, the current study has aimed to verify the output of shear capacity of angle shear connector according to the input provided by Support Vector Machine (SVM) coupled with Firefly Algorithm (FFA). SVM parameters have been optimized through the use of FFA, while genetic programming (GP) and artificial neural networks (ANN) have been applied to estimate and pbkp_redict the SVM-FFA models' results. Following these results, GP and ANN have been applied to develop the pbkp_rediction accuracy and generalization capability of SVM-FFA. Therefore, SVM-FFA could be performed as a novel model with pbkp_redictive strategy in the shear capacity estimation of angle shear connectors. According to the results, the Firefly algorithm has produced a generalized performance and be learnt faster than the conventional learning algorithms.
